With the fifteenth and final season of Supernatural premiering in less than a month, The CW has released the first set of official stills from "Back and to the Future," the upcoming season premiere.
The photos show brothers Sam and Dean Winchester examining Sam's wounds, while their longtime friend and partner Castiel appears at a loss for words. However, the nighttime photos from the upcoming episode tease a much more horror-tinged adventure, as the three main characters face hordes of zombies, armed with little more than pieces of cast iron fire fence.
The Season 14 finale concluded with an enraged God unleashing a wave of zombies on the Winchesters after Sam's failed attempt to kill Him. As the world descended into darkness, Sam, Dean and Castiel were last seen surrounded by the ravenous undead.
Judging by the official stills of the trio during the daytime, the zombie apocalypse may be short-lived, though the Winchester Brothers will likely have to answer to divine wrath as the season continues.
Returning Thursday, Oct. 10 at 8 p.m. ET/PT on The CW for its final season, Supernatural stars Jensen Ackles, Jared Padalecki, Misha Collins and Alexander Calvert.
